Setting the Distance between the Bow and the GPS Antenna
You can enter the distance between the bow of your boat and the location of your GPS antenna. This helps
ensure the bow of your boat crosses the starting line at the precise start time.
1 From the starting line guidance gauge, select Menu > Start Line > GPS Bow Offset.
2 Enter the distance.
3 Select Done.
Laylines Settings
To use the laylines features, you must connect a wind sensor to the chartplotter.
When in sailing mode (
Setting the Vessel Type, page 6
), you can display laylines on the navigation chart. Laylines
can be very helpful when racing.
From the Navigation chart, select Menu > Layers > My Vessel > Laylines.
Mark: Sets how the laylines appear on the chart.
Vessel: Sets how the vessel appears on the chart.
Length: Sets the length of the laylines.
Display: Sets how the laylines and vessel appear on the chart.
Setup > Sailing Angle: Allows you to select how the device calculates laylines. The Actual option calculates
the laylines using the measured wind angle from the wind sensor. The Manual option calculates the laylines
using manually entered windward and leeward angles.
Setup > Windward Angle: Allows you to set a layline based on the windward sailing angle.
Setup > Leeward Angle: Allows you to set a layline based on the leeward sailing angle.
Setup > Tide Correction: Corrects the laylines based on the tide.
Setup > Filter Time Constant: Filters the layline data based on the time interval entered. For a smoother layline
that filters out some of the changes in the boat's heading or true wind angle, enter a higher number. For
laylines that display a higher sensitivity to changes in the boat's heading or true wind angle, enter a lower
number.
